Thoughts arose from my case:
I was looking for a lost image in my PC.
I set Filter to Pictures, and enabled Ctrl+Shift+3.
Now, when scrolling down, the images is loading line by line. It takes some seconds to load all images in the current screen.
I don't know if this technically possible, but it will better that while the images is loading line by line, to check and load first what is under the cursor. It will help the user, since the user point the cursor also by the filename text.
Another thing is the suggested Exclude feature.
I think it won't be enough to have:
Exclude/Omit selected
but also
Exclude/Omit Location (Right Click on one image, and "Exclude/Omit Location", will omit whole images in that location. it's actually to omit the containing folder)
Trying to have it currently by typing !"Location" in the SearchBox, not making good, because it resets the place where you scrolled till now, resets to the top, and you need to scroll again the whole way from top to the place you were before.
You want to continue the images checking, from the same place you were before omitting items.
